英文摘要Solid polymer electrolytes (SPEs) attract great attention due to their wide electrochemical stability window, low cost, and excellent processability. However, some obstacles, including their low ionic conductivity, poor solid-solid contact between the SPE and lithium metal electrode, and uneven lithium deposition behavior, hinder their application in solid-state lithium batteries. Herein, a flexible composite solid electrolyte is facilely designed and successfully fabricated by introducing reactive petal-like MoS2 nanosheets to a poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP)/lithium bis(fluorosulfonyl)imide (LiFSI) polymer electrolyte. The addition of petal-like MoS2 nanosheets not only greatly improves the room-temperature ionic conductivity to 2.8 x 10 (-4) S cm(-1) but also decreases interfacial impedance and in situ suppresses lithium dendrite growth. In the resulting solid-state batteries, both rate capacity (137 mAh g(-1) at 0.54C) and cycling stability (Coulombic efficiency in each cycle close to 100% during 200 cycles) are obtained by employing the electrolyte. In addition, the rational mechanism of MoS2 in improving ion conduction and suppressing lithium dendrite growth is suggested.
